fix: zilliqa genesis ds block issue (#81)
* fix: zilliqa genesis ds block issue * fix: rename zilliqa to zilliqalegacy * fix: udpate zilliqa legacy sdk version * feat: add zilliqa chain * fix: some doc * fix: use legacy version for zilliqa handler * put todo * fix(zilliqa): use a newer sdk version * feat: use 17 for zilliqa sidechain id * feat: add zilliqa rounter * dep(zilliqa): use latest version * test(zilliqa): sync header test
